Planet Mars Amazing Facts!
- Largest volcano in the solar system: Olympus Mons (Home of the Greek Gods) – Rises 27 km (16.7 miles) above the surface of Mars. About 3 times as tall as Mount Everest (29,029 feet). Its base is 540 km (335 mi) wide—it would cover the entire state of New Mexico!
- Longest canyon in the solar system: Valles Marineris – This canyon ranges over 4000 km (2490 miles), and can be as wide as 200 km (125 miles) with depths up to 7 km (4 miles). Compare this with the Grand Canyon on Earth, which is 446 km (277 miles) long, 30 km (18 miles) wide and 1.6 km (1 mile) deep. If Valles Marineris were placed on the surface of Earth, it would stretch from New York City to San Diego, California!
